Periodic Trends

Front

What is ionization energy?

Back

The energy required to remove an electron from an atom.

Front

What happens to atomic size as you move down the periodic table?

Back

Atoms get bigger because they have more energy levels.

Front

Which atom has the largest atomic radius?

Back

Francium.

Front

What happens to atomic size as you move across the periodic table?

Back

Atoms tend to get smaller because they have more protons.

Front

What is electronegativity?

Back

An atom's tendency to attract electrons to itself when chemically combined with another element.

Front

What is the trend of ionization energy across a period?

Back

Ionization energy generally increases across a period.

Front

What is the trend of ionization energy down a group?

Back

Ionization energy generally decreases down a group.

Front

What is electron affinity?

Back

The energy change that occurs when an electron is added to a neutral atom.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy decreases.

Front

What is the trend of electronegativity down a group?

Back

Electronegativity generally decreases down a group.
